I am currently a quantitative researcher at Two Sigma. Previously, I was a postdoctoral fellow in the Center of Mathematical Sciences and Applications at Harvard University. My mentor was Prof. Horng-Tzer Yau. I received my Ph.D. in statistics at the University of Chicago in 2020, advised by Prof. Jian Ding, and a B.S. in mathematics at Tsinghua University in 2015.

I am interested in probability theory.
